Description

Technical Field

[0001] The utility model relates to the technical field of film manufacturing, and more specifically, to an environmentally friendly film. Background Art

[0002] Food-grade environmentally friendly film materials are usually used for short-term food sealing. In order to facilitate the separation of a single film material from a rolled film strip, some manufacturers will set tear marks between adjacent film materials to facilitate separation. When a single film material is sealed at the container mouth, the edge of the film material overlaps, which will make the seal loose and fail to achieve the expected sealing effect. Based on this, the utility model proposes an environmentally friendly film. Utility Model Content

[0005] The diaphragm is provided with two second tear marks spaced at an angle of 180°, one end of the second tear mark extends to the edge of the diaphragm, a wrapping portion is formed outside the second tear mark, and one end of the wrapping portion is connected to the diaphragm.

[0006] The utility model is further configured as follows: the other end of the winding portion has a lap portion.

[0007] The utility model is further configured as follows: a tear notch is provided at one end of the second tear mark, and the tear notch is provided on the edge of the membrane.

[0008] The utility model is further configured as follows: a stress relief hole is provided on the diaphragm at the other end of the second tear.

[0009] The utility model is further configured as follows: a third tear mark in the shape of a cross is provided at the center of the diaphragm.

[0010] In summary, the utility model has the following beneficial effects: the environmentally friendly film involved in the utility model, after using a single piece of film to seal the container mouth, tear off the winding part, use the winding part to wrap around the side of the container close to the container mouth, press the overlapping part of the film material, so that the film is tightly sealed, the sealing is good, the overall function is perfect, and the practicality is strong.

[0013] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0014] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See also Figure 1 and Figure 2 As shown, an environmentally friendly film involved in this embodiment includes a rolled film strip 100, wherein the film strip 100 is formed by connecting a plurality of rectangular film sheets 1 end to end, and a first tear mark 2 perpendicular to the length extension direction of the film strip 100 is provided between two adjacent film sheets 1;

[0017] The diaphragm 1 is provided with two second tear marks 3 with an interval of 180°, one end of the second tear mark 3 extends to the edge of the diaphragm 1, and a wrapping portion 4 is formed on the outer side of the second tear mark 3, one end of the wrapping portion 4 is connected to the diaphragm 1.

[0018] Furthermore, the other end of the winding portion 4 has a lap portion 5 .

[0019] In this embodiment, the separated single-piece film 1 is first sealed at the container mouth, so that the edge of the film 1 is attached to the side of the container near the container mouth (there is an overlap of the edge of the film 1), and then the separation winding portion 4 is torn through the second tear mark 3, and finally two strip-like winding portions 4 are used to wrap around the side of the container near the container mouth, and the overlapping part of the film material is pressed, so that the film 1 is tightly sealed.

[0020] The overlapping portion 5 is provided for mounting, thereby increasing the mounting area and enhancing the connection effect.

[0021] Example 2

[0022] See also Figure 1 and Figure 2As shown, the environmentally friendly film involved in this embodiment is further configured on the basis of Embodiment 1, wherein a tear notch 6 is provided at one end of the second tear mark 3 , and the tear notch 6 is provided on the edge of the film sheet 1 .

[0023] In this embodiment, the tearing notch 6 is provided to facilitate tearing of the second tear mark 3, which serves as a starting point.

[0024] Example 3
